四粒子纠缠态的制作及应用

The Execution and Application of the Entanglement of Four Particle

提出了用三粒子纠缠态通过极化光束分离器 (PBS)来制作四粒子纠缠态的方法 .用四粒子纠缠态可以传送未知二粒子态 .与三粒子纠缠态相比 。

A scheme was proposed which can execute the entanglement of four particles from the entanglement of three particles by polarization beam splitter.It can teleporta unknown state from the entanglemet of four particles.In contrast to the entanglement of three particles,the entanglement of four particles has a more extensive use.
